Other Faults on This Variant
Severe Water Ingress into Boot and Cabin
ModerateThe Mk1 Toyota Aygo (and its siblings the Peugeot 107 / Citroen C1) are infamous for leaking water like a sieve into the boot and rear footwells.
Air Conditioning Condenser Leak (Stone Damage)
MinorThe air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
